How Does A Hard Drive Work - Explain That Stuff

The platters are the most important parts of a hard drive. As the name suggests, they are disks made from a hard material such as glass, ceramic, or aluminum, which is coated with a thin layer of metal that can be magnetized or demagnetized.A small hard drive typically has only one platter, but each side of it has a magnetic coating.
